First time posting here so am not sure how exactly to format this or ask this. Simply I am trying to plot the step response of a given transfer function but I keep getting an error stating "Error using DynamicSystem/step (line 95) Cannot simulate the time response of improper...
For this example, create a tf model that represents the transfer function. You can similarly plot the step response of other dynamic system model types, such as zero-pole gain (zpk) or state-space (ss) models. Get sys = tf(4,[1 2 10]); Plot the step response. Get step(sys...

However, as the ramp signal is one order higher than step signal, the step input signal can be used to obtain the ramp response by dividing the transfer function by s and then evaluating it using the step command. If the given transfer function of system is...
For this example, create a tf model that represents the transfer function. You can similarly plot the impulse response of other dynamic system model types, such as zero-pole gain (zpk) or state-space (ss) models. sys = tf(4,[1 2 10]); Plot the impulse response. impulse(sys) The...
